"a citizen of the UnitedStates, residing at' Ypsilanti, in the countyof WVashtenaw and State of Michigan, have invented certain new andu seful Improvements in Automatic Decarbonizers; andI do declare the following to be afull, clear, and exact. description of'the invention, such' as will enable others skilled in the art'towhich it appertains to make and use the same. I

' decarbonizing devices for use in connection PP QQf the motor; I

with internal combustion engines.

The principal object of the inventionis to produce a/ decarbonizer of" simple design starting and stopping with the "starting or carbonizer'of unitary construction which'maybe very easily" nstalled. Y

carbon- Still another object is to proviig; an inn-'- proved strainer foru'se with the izer.

With these aiid"many" other objects in view, my invention resides '111" the novel teatures of construction, combination and ar rangement of parts whichwvill behereinafter 1 more particularly described and claimed and shown in'the drawings wherem:

Figure 1 is a side elevation partlyin secmaterial removed.

In the drawings my improved device is shown applied to the intake manifold I of an ordinary internal combustion engine, the manifold preferably being tapped at any suitable point between the engine cylinders and the throttle valve for the insertion of The device comprises vVAL'rEZR BEACiLJOSLYN, oF YrsiLANTI, MICHIGAN steam by the heat of the combustion of the gaseswithin the engine cylinders This steam or vapor prevents the formation of carbon and also tends to loosen anyold deposits of carbon which have accumulated on the pistons or cylinders.

tioned cylindrical casing 3 having its upper end closed as shown at 4, while its lower end is open as at 5 and internally threaded.

One -side of the casing is provided with a This invention relates to improvements in relatively large opening 6, while smaller openings 7 are formed in the sides of the casing at right anglesto the opening 6. Disposedwithinthe casing3' is a transparent glass cylinder 7' open at both ends, the

upper end of said cylinder having a watertight connection with the casing by means of 'a suita-ble washer 8: The cylinder 7 i is An additional "object is to provide a de-' forced against this washer 8 by means of a bushing 9 which is threaded inthe lower end of the-casing 3, an'additional washer 8 being disposed between the bottom end of the cylinder and said bushing 9. 'By this arrangementa sight feed is provided-so that the flow of liquid may be readily ascertained. The--bushing 9 is provided. "with an eX= 'ternally threaded nipple 10;. and the pipe 2 is connected thereto by means of a union 1]. This construction of the several parts of the device allows water or other liquid to flow from the casing to the intake manitold I.

"This liquid reaches the casing from a suitable supply tank T through a, downwardly inclined pipe 12 which has its upper end formed integrally with the upper portion of the casing and at the side opposite the opening 6. This pipe 12 extends within the a i s e ification (if new; neat; Patented iota. 11, item. Application filed-October 30.1916. serial-'ua zam.

a vertically positank T and has a flange 13 surrounding the same adjacent its ends, said flange being formed integrally therewith and with said casing. From Fig. 4 it will be seen that this flange is curved to conform to the curvature of the side of the tank T to which it is attached by soldering or the like. ,A web 14 connects the flange and the pipe 12 with the casing so that a very strong yet simply constructed device is provided.

The opening'in the: pipe 12 communicates with a bore 15 which is formed transversely through the top 4 of the casing. Theouter end portion of the bore 15 is enlargedandscrew threaded to receive the threaded porvalve 17 formed on its end for engagement with a valve seat to prevent the flow of liquid from the bore 15 to the bore of a nozzle 18, the latter depending 'from the top .1 within the casing, The nozzle 18 is preferably formed integrally with the top 4 and in order to form the bore thereof a hole is bored through said top 4, this being later closed by the screw orother form of plug 19. The top 4 is further provided with a threaded openingto receive a set screw 20 which holds the valve stem 16 in adjusted positions in its bore.

From the inner end of the pipe 12 extends a tube 21, the lower end thereof terminating adjacent the bottom of said tank T and provided with a strainer through which the water passes into said pipe.

As soon as. the engine is started the vacuumcreated in the intake manifold will automatically suck the fluid from the tank Tthrough the strainer formed on the end of the tube 21, up said tube and the pipe 12, from whence it flows through the nozzle 18 into' the casing, the pipe 2 conveying the liquid from the casing to the manifold. As

. soon as the suction is suspended the operation of the device will be stopped. Any suitable liquid may be used in the tank T, but water has been found to work very satisfactorily since the steam which is created therefrom will very readily soften the carbon within the cylinders and prevent the formation of new carbon. In cold weather a quantity of alcohol may be added to the water in the tank to prevent its freezing.

The device may be further used as an engine primer by substituting gasoleue for the water within the tank. From the foregoing description it will be obvious that I have invented an extremely simple device.'easy of application. which can be manufactured at a slight cost, and yet which will be very ellicient in operation.

I claim:

The combination of a tank having an aperture in its side, a casing having a downwardly inclined integral portion extending through said aperture, said casing having an open bottom, analperture in its side, and a transverse bore extendingthrough its upper end. said bore being decreased at its inner-end to provide a valve seat, valve in the outer end of said bore to coact with said seat, a downwardly inclined pipe secured to said integral extension and having its upper end communicating with the inner end of said transverse bore, the lower end of said pipe terminating adjacent to the bottom of said tank. a transparent cylinder in said casingfsaid cylinder to form in connection with the opening in the casing a sight feed, a nozzle, depending from and integral with the top of the casing within said transparent cylinder, and a connection between the open bottom of the casing and the intake manifold of an internal combustion engine.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
